## What is the volume of by solution formed by mixing 25 mL of isopropanol with 45 mL?

Adding 25 ml IPA to 45 ml H₂O gives 67.8 ml of solution, not 70 ml. You can solve the problem by looking up the densities of IPA and H₂O and calculating the mass percent IPA (30.4\%), using that to find the density of the IPA solution (0.952).

## What is the percent by volume of isopropanol in a 90 mL solution that contains 25ml isopropanol?

What is the percent by volume of 25ml alcohol in 120ml solution?

The percent by volume of ethanol in this solution is about 29\%.

How do you find the percent by volume of a specific solution?

Calculating Percent Volume/Volume (\% v/v)

1. A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):
2. \% v/v = mL of solute/100 mL of solution.
3. Example:
4. X \% = 5.0 mL HCl/100 mL of solution.
5. X/100 = 5.0/100.
6. 100X = 500.
7. X = 5.0\% \% v/v.

### What is IPA 70\%?

70/30 IPA (Isopropyl Alcohol) is a low toxicity solvent made of a mix of 70\% pure isopropyl alcohol and 30\% water. This is generally the mixture used in first aid products such as rubbing alcohol.

### What is the percent by volume of isopropanol?

For example, when you buy isopropanol at the store (rubbing alcohol), you’ll notice that it says 70\% (vv), which means by volume. This tells you that the solution is 70\% isopropanol. So, returning to our rubbing alcohol, 70\% (vv) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol.

What is percent by mass concentration of the solution?

Mass Percent: The mass percent is used to express the concentration of a solution when the mass of a solute and the mass of a solution is given: Mass Percent=Mass of SoluteMass of Solution×100\%

## What is the percent by volume of a 90ml solution that contains 25ml methanol?

1 Expert Answer So, you have 90 mls of total solution, and of that, 25 mls is isopropanol. The \% by volume = 25 ml/90 ml (x100\%) = 27.8\% by volume.

## What is the percent by volume of ethanol in a solution?

Example: when 52 ml pure ethanol is mixed with 48 ml of water a volume of 96.3 ml is obtained instead of 100 ml….Ethanol concentration table: what is the percentage by volume or weight?

What is volume by volume percentage?

Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution. It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100. Examples: Wine has a typical alcohol content (v/v percent) of 12 percent.

How do you find the percent of a solution?

One way to describe the concentration of a solution is by the percent of a solute in the solvent. The percent can further be determined in one of two ways: (1) the ratio of the mass of the solute divided by the mass of the solution or (2) the ratio of the volume of the solute divided by the volume of the solution.
